The plot below shows the number of new COVID cases by state. Note that each figure has its own y axis; this is done so that trends can be seen within each state. Log scales can make the difference between 100 and 1000 cases hard to discern and a common y axis causes states like NY and CA to swamp states like NC. Negative new cases can occur when States revise their total number of cases downwards, as Hawaii did between June 30, 2020 and July 1, 2020.
This figure shows the number of COVID cases per 1,000.

According to the WHO the positive rate should be below 5%.2 Days above the threshold are denoted in red, days below are in blue. Note that the variables currently used for these plots –positiveIncrease and negativeIncrease– are being phased out and will be replaced by positiveCasesViral and negativeCasesViral. Each dot represents the rolling average of tests within the previous week (this approach smoothes out trends such as fewer cases being reported on weekends).
The two sets of points are confirmed cases (black), and potential cases (grey) which are confirmed cases times ten. For herd immunity, typically 70-90% of a population needs immunity.3
